Abstract

The results of deep oxidation of toluene on polyoxide nickel-, copper-, chromium-containing catalysts supported on 2 % Ce/?-Al2O3 are presented in the paper. Effect of process parameters (temperature, space velocity, concentration of toluene in a gaseous mixture) on the completeness conversion of toluene(to CO2 and H2O) on polyoxide catalyst has been studied. Polyoxide Ni-Cu-Cr catalyst supported on 2 % Ce/?-Al2O3 in oxidation of toluene at space velocity of 5×103 h-1, 723 - 773 K and 320 mg/m3 toluene content in initial mixture provides 98.8 % toluene conversion to CO2. The presence of CeO2 crystals and X- ray amorphous clusters (d = 20 – 100 Å) of the oxides of metals of variable valence NiO, CuO, and solidsolutions of metals CuO (NiO) on the surface of Ni-Cu-Cr/2 % Ce/?-Al2O3 catalyst calcined at 873 K was installed by X-ray diffraction and electron microscopy.
